This data release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in semi-arid eucalypt woodland using eddy covariance techniques. It been processed using PyFluxPro (v3.3.0) as described in Isaac et al. (2017), https://doi.org/10.5194/bg-14-2903-2017. PyFluxPro takes data recorded at the flux tower and process this data to a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). For more information about the processing levels, see https://github.com/OzFlux/PyFluxPro/wiki.

The Collie flux station was located approximately 10km southeast of Collie, near Perth, Western Australia. It was established in August 2017 and stopped measuring in November 2019. 
Credit
We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. The Collie Flux Site was managed by the University of Western Australia. The flux station was part of the Australian OzFlux Network and the international FLUXNET Network. 
Purpose
The purpose of the Collie flux station was:
to provides nationally consistent observations micrometeorology (climate, radiation, fluxes of carbon and water).
to provide long-term measurements as part of the OzFlux network
The tower was a component of the UWA critical zone observatory.
